Fresh off a $ 150 million round of funding, kids’ gaming platform Roblox is making its first acquisition. The company says it’s acquiring the small startup PacketZoom, bringing its team and technology in-house to help it improve mobile application performance as its platform expands further into worldwide markets.

Founded in 2013, and based in San Mateo, California, PacketZoom had raised a $ 5 million Series A late last year. The company combines a content delivery network (CDN) to speed up performance with an application performance management tool to identify issues in a single package, TechCrunch had explained at the time.

The company’s products allow developers access to analytics about the app and network-performance related issues, as well as optimize app delivery and content downloads – up to 2 to 3 times faster.

The system in particular is designed to overcome the limitations of slow and unreliable networks, like those found in emerging markets. It also helps to ensure faster and lower latency data transfers worldwide.

It’s clear how this acquisition makes sense for Roblox, which offers a platform where kids create and play in 3D worlds and games and has global expansion in mind. With PacketZoom integrated into its gaming platform, users will be able to join games faster and have a better experience when playing on mobile devices.

Roblox had said earlier this year it was cash-flow positive and continues to be profitable. It raised funds in order to stock its war chest and have a buffer, while focused on its international expansion efforts. It also said it would use the funds to make acquisitions and open offices outside the U.S. in some regions, like China.

According to PacketZoom’s website, it was working with customers like Glu Mobile, Sephora, Photofy, Inshorts, Upwork, News Republic, Wave, Belcorp, GOTA, Netmeds, Houzify, Wooplr, Fluik Entertainment, Wondermall, and others. These relationships will be wound down, as Roblox plans to only use the IP internally, not to support other customers.

Roblox declined to speak to the acquisition price, but notes it was an all-cash deal. It includes all of PacketZoom’s IP and code. PacketZoom’s founder and CTO, Chetan Ahuja, along with the PacketZoom’s four-person engineering team will join Roblox.
